One thing that did catch my eye, though, is the line in the crawl: “With the support of the REPUBLIC, General Leia Organa leads a brave RESISTANCE.” Is that really the case? The relationship between the two was admittedly ambiguous in this film. And that’s something I’m less critical about after considering that the state of the senate is similarly mostly glossed over in the first Star Wars film.

Today is the end of the Republic!
The end of a regime that acquiesces
to disorder! At this very moment,
in a system far from here the New
Republic LIES to the GALAXY while
secretly supporting the treachery of
the loathsome Resistance. This fierce
machine which you have built, upon
which we stand, will bring an end to
the Senate! To their cherished fleet!
All remaining systems will bow to
the First Order! And will remember
this… as the last day of the
Republic! - General Hux

I think this tells all about the relationship.
